TYPE-CASTING MACHINE.

Specification of Letters Patent.

Patented Aug. 7, 1996.

To It w/mm/ if 1111/17 conceive:

Be it known that I, HERBERT STERLING VVrLsoN, a citizen of the UnitedStates, and a resident of the city of Kirkwood, county of St. Louis, andState of Missouri, have invented certain new and useful Improvements inType-Casting Machines, of which the following is a specification.

My inventionrelates to machines for making type; and it consists in theparts and in the arrangements and in, the combinations of partshereinafter claimed.

In the accompanying drawings, which form part of this specification, andwherein like symbols refer to like parts wherever they occur, Figure 1is a side elevation of my machine. Fig. 2 is a plan thereof. Fig. 3 is avertical end view, partly in elevation and partly in section. Fig.- 4 isa longitudinal cross-section. Fig. 5 is a plan view of the mold-coverand portion of the mechanism adjacent thereto. Fig. 5 is a verticalsectional detail through the mold-cover and its guideway. Fig. 5 is aperspective view of one of the wedges for adjusting the mold-coverguides. Fig. 6 is a plan detail of a matrix-box andits carrier. .Fig. 7is a detail end elevation of said matrix-box. Fig. 8 is across-sectionaldetail of the friction-clutch on the line 8 8 of F ig. 9. Fig. 9 is avertical detail of the fric- 'tioibclutch and power-transmittingdevices.

Fig. 10 is a plan view of the machine-with certain parts removed. Fig.11 is a vertical view, mostly in elevation, of the pump mechanism. Fig.12 is a vertical view, mostly in elevation, of the pump mechanism in aplane at right angles to the view of Fig. 11. Figs. 13 and 14 are detailviews of the pump-actuating mechanism.

The main shaft 1 of the machine is journaled horizontally in the mainframe 2 and preferably is arranged transversely to the line of motion ofthe mold-cover 3. The mold-cover 3 carries a spring 3, the typeejectingplunger 3", arranged to cooper ate with an anvil 3",'and a type-grippingjaw 3 all of which are more fully described in a pending application ofWilliam A. Schraubstadter, Serial No. 154,130, filed April 24, 1903.This main shaft is driven by any suitable 1notor'-as, for instance, bymeans of an electric motor 4, whose shaft 5 (see Fig. 9) is slottedlengthwise and has a sleeve 6,1novably secured thereto by a feather I orspline fitting in said slot. This sleeve has two pinions of differentdiameters at its respective ends, which pinions are arranged. to

intermesh with corresponding pinions 8, fixed on a counter-shaft 9. thecounter-shaft are farther apart than the sleeve-pinions,so that only onepair Will intermesh at a time, whereby the speed of the counter-shaft isgreater orless, according as its smaller or larger pinion is in workingengagement with a motor-pinion.

The counter-shaft has a slotor spline 1O extendin lengthwise thereof andhas a splined or slotte friction-wheel 11, arranged to turn with thecounter-shaft and still be free to move longitudinally thereof. The mainshaft is arranged at right angles to the counter-shaft and has afriction-disk 12 fixed thereto in position for the friction-wheel 11 tobear against its face, and thereby transmit motion from thecounter-shaft to said main shaft.

In order to regulate the speed of the main shaft, a threadedrod 13 isjournaled in the framework parallel with the'counter-shaft. This rod hasa hand-wheel'14 at its outer end in convenient reach for manipulationand has a threaded nut 15 working on its threaded en This threaded nuthas a forked arm 16 projecting therefrom to enter an annular groove 17provided therefor in the peripherv of the extending hub 18 of thefriction-wheel. As the forked arm of the nut straddles the hub, it isprevented from turning with its rod 13, and consequently the turning ofsaid rod causes the endwise movement of the nut, which carries with itthe friction-wheel 11, and thereby changes radially of the disk 12 thepoint of its engagement with the friction wheel. By this arrangement thepower is transmitted, through the intermediate connecting ortransmitting devices, from the motor to the main shaft 1 of the machine.The main shaft has a pulley l9 fixed thereon, and over this pulleypasses an endless belt 20 which is kept taut by any suitable belt-tightener 21, which is omitted from the detail view of Fig. 9. This belt 20also passes around a second pulle 22 on a shaft 23, journaled in thefarmewor parallel with the main shaft. This last-mentioned shaft 23 hasfixed thereto a number of edge cams and is hereinafter denominated thecam-shaft.

The pinions on i The pulley 22 is mounted loosely on the these arms havepms or projections 28, which cam-shaft, but transmits motion thereto byI means of a friction-clutch within the. control 5 of the operator. Forthis purpose the face of the pulley is undercut, and within theoverhanging rim thereof are arranged curved friction-blocks 24, adaptedto bear against the inner surface of said rim. The ends of j thesefriction-blocks are connected together by tension-springs 25, which tendto hold the blocks out of contact with the pulley. Fixed to thecam-shaft is a momentum-wheel 26, which has inwardly-extending arms 27pivoted near its periphery. The free ends of extend laterally intoposition to bear against the backs or inner surfaces of the respectivefriction-blocks. Each of the pivoted arms has a threaded bolt 29extendingradially therethrough, so as to be adjustable. Arranged in thesame plane with said bolts is a cam-disk 30, loosely journaled on thecamshaft. The periphery of this disk has an eccentric projection foreach bolt and arranged to cooperate therewith. This disk thusconstitutes a cam and is provided with a radial arm 31, having ahandpiece 32 on its outer end.

When .the disk is turned in one direction, its cam-surfaces bear againstthe respective bolts, and thereby cause the arms to swing outwardly andforce their friction-plates against the inner rim of the belt-pulley, inconsequence of which the cam-shaft broughtv into frictional engagementwith the belt-pulley and moves therewith. TV hen the disk is moved inthe opposite direction, or when the disk is prevented from moving withthe belt-pulley, the pressure is removed from the friction-blocks andthe helical springs immediately pull the friction-blocks away from thebelt-pulley, and thereby disengage the cam-shaft from said belt-pulley.The clutch thus described has the immediate advantage of being easilyoperated byhand while the machine is in full operation.

In order to quickly stop the machine when it is running rapidly, it isdesirable to provide a friction-brake therefor. This frictionbrakeconsists of a hand-lever 33, fulcrumed in the frame and having a portionthereof curved to conform to the periphery of the momentum-wheel. Thislever has a piece 34 projecting therefrom in position to be moved intothe path of the handle 32 of the frictiondisk 30. Normally thehand-lever is out of contact with all of the moving parts of themachine; but when it is desired to stop the machine the free end of thehand-lever is raised so as to bring its projection 34 into position toobstruct the movement of the friction-disk and so asto have its curvedfriction-surfacebear against the periphery of the momentum-wheel. Thefriction-clutch is thus automatically released simultaneously with theapplication of friction to the momentum-wheel, whereby the braking ofthe nmchine proper is effected silmlltaneously with the cutting off ofthe power therefrom.

In order that the mold-cover may reciprocate horizontally in guidesprovided therefor on the frame of the machine, said mold-cover has avertical opening 37 therethrough, through which projects the arm orlever 36, whereby it is reciprocatedp This arm has a transverse opening37 therethrough, which opening is of a circular form at its lowerportion and has a straight offset portion of less diameter extendingupwardly. The moldcover pin 38 is a cylindrical bar of proper sizetopass through the circular portion of the opening '37, and its middleportion is flan tened so as to allow it to extend up into the reducedportion of said opening. Said moldcover pin 38 is thus locked in place,and its cylindrical ends project so as to overlap the upper surface ofthe mold-cover and cooperate with grooves or bearing-surfaces providedtherefor on the mold-cover.

The lower end of the arm 36, which actuates the mold.cover, is pivotedon the end of a lever 39 near the bottom of the machine. Thislast-mentioned lever 39 has a strong spring 40 pressing downwardlyagainst the end thereof to which the mold-cover-actuating arm isconnected, and the-other end of said lever projects outwardly inposition to be actuated by the foot of the operator. When it is desiredto remove themold-cover for'dressing, the actuating-arm is raised by thefoot of the operator, thus leaving both his hands free for the propermanipulation of the. mold-cover pin.

The mold-cover-actuating arm 36 has a yoke 41 straddling the cam-shaft23. The two sides or legs of said yoke are offset later ally from eachother and each is provided with. a roller 42 for cooperation with a camprovided for it upon the cam-shaft. The two cams 43 44 are arranged atdifferent longitudinal positions on said cam-shaft, so that each camoperates only upon one of said rollers. The cam 44, which causes theforward movement of the mold-cover, is ar ranged to have a long pause,and the cam which causes the backward movement thereof is arranged tohave a short pause. By this arrangement the rotation of the cams causesthe reciprocation of the mold-cover with definite intermissionsaofmovement. The pauses thus provided for allow ample time for the othermovements necessary in the formation and ejecting of the type. Thisactuating-arm is made in sections adjustably connected together, so asto vary the alinement of the sections with reference to each other andalso vary the length of said arm. For this purpose the lower section hasa screw or threaded bar 45 fixed in its upper end to project upwardlytherefrom into a hollow projection or hub 46 at the lower end IIC of theupper section. The lower surface of this projecting hub 46 has a concavesurface which fits over the convex surface of a block 47, mounted on thescrew and supported thereon b means of a nut 48, which works on thethread of the screw. By this arrangement the turning of the nut variesthe length of the actuating-arm.

Pivotally mounted on the upper section of the actuating-arm on oppositesides of the shaft are links 49, whose lower ends are threaded and havenuts 50 working thereon. These links extend through laterally-projectingportions of the lower sections and are clamped thereto by means of thenuts. By this arrangement the alinement of the upper section withreference to the lower section is varied according to the adjustment ofthe nuts, the curved bearing of the sections against each otherpermitting such change of alinement.

The guides for the mold-cover comprise long gibs or bars v51. The faceof the upper portion of the gib next to the mold-cover is paralleltherewith; but the lower portion of said face is set at a slightinclination to the line of motion of said mold-cover. (See Figs. 5 and5.) Between the lower inclined portion of each ofsaid gibs and the frameis an elongated wedge 52 with its end outturned. Extending through ahole in such outturned end is an adjusting-screw 53, which Works in athreaded hole provided therefor in the end of the gib. By thisarrangement each wedge may be adjusted to any desired position, and aset-nut 54 on its screw will hold it wherever adjusted.

It is necessary to dress the surface of the mold-cover from time totime, and for this purpose it is desirable to make said moldcoverremovable and have it made without projecting parts on thewearing-surfaces. For this purpose the rear end of the moldcover israbbeted transversely on its under side to secure thereto adownwardly-projectting block 55, made in two parts. (See Fig. t.) Thisblock has a threaded hole therethrough, through which extends a threadedbolt 56. in position to strike against an abutment-plate on the frame ofthe machine, and thereby limit the forward movement of the mold-cover.In accordance with common practice the mold-cover and the ortions of themachine adjacent to the mol are made hollow and connected to thewater-pipes 57 for cooling them.

The mold 58 is of the usual construction, and the matrix 59 is mountedin a matrixbox 60, which is supported upon a matrixcarrier arm 61. Thismatrix-carrier arm is mountedupon a frame 62, arranged to slide inguides provided therefor in the main frame transverse to the line ofmotion of the mold-cover and arranged to be reciprocated by means of acam 63 on the cam-shaft. For

this purpose a vertically-arranged rockshaft 64 (see Figs. 3 and 5) hasan arm 65 fitting into a groove in the periphery of the cam 63 and asecond arm 66 arranged to actuate the sliding frame. The lower portionof the matrix-carrier arm 61 is pivot-ally connected to the end of ahand-lever 67, which is fulcrumed on the sliding frame 62. An upperportion of this matrix-carrier arm is pivotally connected to saidsliding frame by a link 68, said link being of equal length with thesupporting end of said lever and parallel therewith, whereby thematrix-carrier arm will move vertically without canting.

Against the handle of the lever 67, which supports the matrix-carrierarm, bears a spring 69, provided therefor on said sliding frame. Thissliding frame also carries a second hand-lever 70, arranged to cooperatewith the above-mentioned hand-lever 67 for the convenient manipulationof the matrixbox and matrix. The sliding frame 62 also carries a spring71 for bearing against it and an adjustable back-stop 72 for limitingits position. This last-mentioned lever has a thrust-bar 73 connectedthereto by a balland-socket joint, and this thrust-bar bears upwardlyand forwardly against the matrixbox on the matrix-carrier arm. Thehandles of the two hand-levers are far enough removed from the mold toremain cool, in consequence of which the matrix may be removed andreplaced with another matrix without waiting for it or the,other heatedparts to cool off. The handles of the two hand-levers are arranged closeenough together to be grasped by a single hand, wherey the pressure maybe removed from the mold and the slide withdrawn by the hand whichgrasps said handles, and the other hand is left free to manipulate thematrix.

Upon the matrix-carrier arm are two pins or projections 74, and upon thematrix-box are elongated offset projections 75, arranged to constitutehooks for interlocking with said pins during the return movement of thematux-carrier arm. By reason of the loose.

mounting of the matrix-box and the upward, lateral, and longitudinalpressure thereon of the resilient parts said matrix-box is pressed intothe angle formed by its abutments, which serve to position it withreference to the mold. This automatic positioning of the matrix-boxoccurs while the sliding frame is in its outer position. )onsequentlywhile the sliding frame is being moved inward to exert pressure on thematrix during the casting of the type there is no tendency of the matrixto tilt or cant from its proper position.

To the base of the mold is secured a piece 115, which projects above thematrix-box and constitutes the top stool therefor. The under side ofthis top stool is made smooth and flat, so that then per face of thematrixbox will slide smooth y thereon. The lower 45 pose.

55 jet-orifice.

side of the matrix-box is extended rear-' wardly and provided with lugs116 on the under side of such extension. A pintle 117 extends throughthese lugs and through lugs 5 118 provided therefor on the bearing-plate119, whereb said bearing-plate is pivotally secured to t e matrix-box.The front portion of this bearing-plate is of increased thickness inposition to bear upwardly against the 10' matrix. Bythis arrangement theupward pressure of the s ringressed carrier-arm 61 1s transmitted, t onthe enlargement of y the bearinglate, to t e matrix and its box,

so as to'hol it firmly against the top stool :5 115, and as there isonly a small area'of contact between the carrier-arm and thebearingplate inequalities in the surface of saidarm are unim ortant anddo not cause any alteration of t e normal relation between the ma- 2otrix-box and the top stool.

The meltin pot is mounted u on a horizontal arm or bracket 76, pivotallymounted upon the framework so as to swing horizontally. The melting-pothas a raised hollow :5 hub 77 therein, constituting a cylinder in whichworks a plunger or piston 78. The lower end of this cylinder isconnected by a passage-way 79 to a chamber 80 near the side of themelting-pot, with which'chamber the jet-orifice 81 communicatesdirectly. This chamber is arranged horizontally and has a pin or plugvalve 82 arranged therein to close ando en the ni ple-orifice. The oposite end 0' said chamber has an opening t erein --3 communicati'ngdirectly with the hollow interior of the melting-pot.

The edge of this 0 enin inside of the valve-chamber is beve ed 0 .toconstitute a seat for a valve 83, mounted upon the bar 84, which carriesthe 49 pin or plug valve 82 at the opposite end of said chamber. Thisbar 84 is mounted in any suitable guides provided therefor in themelting-pot and is reciprocated b means of an arm or crank-pin 85,provided or the pur- At the forward end'of the stroke of said bar the inor plug valve 82 closes the jet-orifice, w 'le the other valve 83 isremoved from its seat to open'communication between the valve-chamberandthe melting- 5o-- pot, and thereb permit the molten metal to multaneouswith the closing of the jet-orifice. The plunger thus constitutes apumpfor forcing the molten metal into the mold. The

mechanism for accomplishing this opera- 6 5 tion is as follows: Theplunger 78 has an up the jet- 6 orifice and the lifting of the plungeris si-- ward extension, which passes through guides extending upwardlyfrom the melting-pot for the purpose. A coiled spring 87 surrounds theupper end of said plunger rod or stem 86 and bears at one end againstthe guide-supports and at the other against a nut 88, secured on the topend of said plungerrod, whereby said spring tends to hold said plungerin its uppermost position. Pivotally mounted upon the melting-pot is ahorizontal lever 89, one end of whichengages the stem 86 of the plungerand the other end of which is connected. to a vertical rod 90. Aroundthis vertical rod is a coiled spring 91, whose upper end bears against ashoulder on said rod and whose lower end bears against a stationary partof the frame or bracket, whereby the spring tends to keep said rodnormally in its uppermost position. The lower end of said rod extendsthrough the 'bracket and is enlarged into a head or flange. Mounted inguides provided therefor on the main frame of the machine is averticallymovable bar 92, whose up er end extends laterally and isbifurcate in position to straddle the vertical rod 90 and engage theenlarged head or flange thereof. This lastmentioned bar 92 is pivotallyconnected to one end of a lever 93, which is fulcrumed in 'the mainframe and whose other end carries a roller 94 in position to bearagainst a cam 95, mounted upon the main cam-shaft of the machine or upona shaft specially provided for the purpose. By this arrangement thecoiled spring 91 causes said roller 94 to bear is affixed a secondcrank-arm 97, which is connected by a link 98, containing a turnbuckle99 or other means for varying its length, to a bar 100, arranged toslide vertically in the frame of the bracket. The lower end of this baris bent horizontally to form a bearing-face for the end of a pin 101,which fits loosely in a hole provided therefor in the frame of themachine. The lower end of this pin rests upon the top side ,of a lever102, fulcrumed in the main frame and carrying a roller 103, arranged tobear against a cam 104, provided thereforon the cam-shaft or upon ashaft specially provided for the urpose.

In order tokeep the rol er 103 in contact withits cam, a spring 105 isarranged to exert a downward pressure thereon. This spring surrounds arod 106, which is vertically movable ,in the bracket frame and bears atits upperend against said bracketframeand bears at its lower end againsta shoulder or adj'ustablamut 107, mounted on said rod. The lower end ofsaid rod 106 bears against the laterally-extending portion of the bar100, whereby thepressure of pot bracket is swung toward the mold the g.cdgeo'f the bar will ride up over the end of T the pin -10], and thusautomatically make an operative connection therewith. When themelting-pot bracket is swung away from the mold, the connection betweenthe pumpvalve and the operating mechanism is automatically disengaged.

In order to render the connection of the,

pump-valves to the driving mechanism inoperative, even when themelting-pot is in proper relation to the mold, it is only necessary toremove the ower-transmitting pin, which removal is eilected merely bylifting the pin out of the hole provided therefor.

In order to adjust the jetnozzle to its proper position in alinelnentwith the mold, the pivot or fulcrum of the melting-pot is made in theform of an eccentric 108, which is itself pivotally mounted on a spindleor shaft 109 provided therefor. This shaft is provided with a hand leveror arm 110, whereby it may be turned to any desired position, therebyshifting the entire meltingpot bracket toward or away from the center ofthe shaft. This eccentric thus constitutes the means for adjusting thejet-nozzle longitudinally or in the direction. of the movement of themold-cover.
